A pressing device for extracting water from a pulp web comprises two press rolls that form between them a nip and that are arranged to extend substantially in parallel one to the other in the unloaded condition. The first press roll has its two ends supported in first bearing blocks and is stationarily fixed in the axial direction at least on one end. The second press roll is supported by its two ends in two bearing blocks. The first bearing blocks and the second bearing blocks can be braced one to the other by tension members which allow the press rolls to perform a relative movement in the axial direction under load. One of the second bearing blocks is secured against displacement in the axial direction on the lower first bearing block, by an articulated joint acting preferably on the middle of the longitudinal extension of the tension element. This minimizes the bending stress exerted on the tension elements and distributes it uniformly over the two ends of the tension elements, provided a central point of attack is selected for the articulated joint. |
